摘要：

Production cross sections for t (t) over bar and t (t) over barj events at hadron colliders are calculated, including finite-width effects and off resonance contributions for the entire decay chain, t-->bW-->blnu, for both top quarks. The resulting background rates to a Higgs boson search at the CERN large hadron collider are updated for inclusive H-->WW studies and for H-->tautau and H-->WW decays in weak boson fusion events. The finite-width effects are large, increasing t (t) over bar (j) rates by 20% or more, after typical cuts which are employed for top-background rejection.
